Analysis of decanter centrifuge from the material nature

 

There are many types of decanter centrifuges, and each type has different characteristics and scope of application. Therefore, it is a very important issue to properly select the appropriate decanter centrifuge according to certain process requirements and technical conditions. The selection of decanter centrifuge is mainly considered from two aspects. The first is the nature, composition of the separated materials, and the second is the technological requirements and economic rationality of the separation process:

Decanter-Centrifuge-For-Sewage
I. Consider from the nature and composition of materials

The primary basis for selection is the type of heterogeneous system that is separated. For example, for the separation of emulsions in a liquid-liquid system, the first consideration is to use a centrifugal separator. For liquid-solid systems, when the liquid phase of the suspension is a loose material with a low degree of solidity, large solid phase concentration, and coarse particle size (> 100um), various filter decanter centrifuges can be considered. Generally speaking, this kind of decanter centrifuge can get drier filter residue and better washing conditions. Secondly, it is necessary to further select the appropriate form for specific conditions.
If the suspension is a material with a large liquid phase viscosity and a fine solid particle size, it is easy to block the filter cloth or screen, but it is difficult to regenerate. Therefore, a centrifugal sedimentation decanter centrifuge should be used. When the solid phase concentration is large (5% to 10%), a spiral discharge sedimentation decanter centrifuge can be used. If the solid phase concentration is less than 1%, a tubular high-speed decanter centrifuge or a chamber decanter centrifuge can be used. If the solid phase concentration is 1% — 5%, a disc decanter centrifuge can be used. The automatic slag-discharging dish decanter centrifuge can obtain flowing concentrated sediment, so it is often used for solid-phase concentration. For liquid-liquid-solid three-phase systems, generally the solid content is not high, you can use a dish decanter centrifuge.

2, from the technical requirements of the separation process

The process requirements of the separation process directly affect the selection of the decanter centrifuge. For example, the separation process requires intermittent or continuous operation. The minimum particle size of the separation, the liquid content of the filter residue, the clarity of the filtrate, the discharge method, whether the solid particles are allowed to be destroyed, and washed Requirements, the length of the operating cycle and whether automatic control is required, the degree of automatic control, etc.
In addition, there are still requirements for sealing, anti-corrosion and explosion-proof.
In short, it is necessary to choose a decanter centrifuge that is inexpensive, applicable (that is, in line with process requirements), simple to manufacture, and easy to maintain. Choose according to the main contradictions that need to be resolved and make economic comparisons. Both technical possibilities and economic rationality must be considered. Of course, according to human operation, there are also manual operation and automatic operation. Users can choose according to their needs.

Introduction of iquid-ring layer thickness of decanter centrifuge

The thickness of the liquidring layer is an important parameter for the optimization of Decanter centrifuge, which directly affects the effective settling volume of the decanter centrifuge and the length of the drying area (shore area), and then affects the sludge dewatering treatment effect. Generally, it is realized by manually adjusting the height of the liquid level baffle in the stop state. When adjusting, the height of each liquid level baffle must be consistent, otherwise it will cause severe vibration during the operation of the decanter centrifuge, and some foreign manufacturers’ products can realize automatic adjustment of liquid-ring layer thickness.

Decanter-Centrifuge-Sewage-Sludge

By increasing the thickness of the liquidring layer will increase the sedimentation area and the residence time of the material in the Decanter centrifuge will increase accordingly. The quality of the filtrate will be improved as well. On the contrary, by lowering the thickness of the liquid-ring layer can obtain a higher mud cake of solid content, but this will be at the basic of the filtrate quality lost.

Therefore, the height of the liquid level baffle should be adjusted reasonably to achieve the best combination of mud cake degree and filtrate quality. In general, many decanter centrifuge suppliers have adjusted the liquid level baffle in advance when the machine leaves the factory. However, due to different conditions on the site, if the operating status of the decanter centrifuge is not ideal, you can communicate with the equipment engineer to make adjustment to the on-site liquid level baffle.
